Title: Frame strip system
Inventor: ODAKA MASAAKI
IPC: H04L12/28
Filed: 1989-03-14
Abstract: PURPOSE:To prevent an unnecessary information frame from being circulated on a ring by using the content of the origin of call address holding means and eliminating an information frame returned while being circulated through the token ring when the frame is a relay information frame sent by itself. CONSTITUTION:When the information frame originated from a node 12 in a LAN 1 is sent as a relay information frame to a LAN 2 via a node 10, an SA field in the relevant relay information frame is stored in a register (a) in the node 10. When the relayed information frame is returned while being circulated through the LAN 2, the SA field in the information frame is compared with the origin of call address stored in shift registers (a)-(n) and when they are coincident, the frame is eliminated. Thus, the node 10 sends frames of n-set or below before the token is sent.

Abstract: PROBLEM TO BE SOLVED: To optimize a density of a position detecting mark formed on a transporting belt for color slip correction, in the case of a tandem type, and to make the exact color slip correction possible to be performed. SOLUTION: This device performs the color slip correction among respective colors by forming density controlling marks 27K and 27M of two colors or more on a transporting belt 7, predicting the density thereof based on an output signal of the density detecting sensor 26, changing the image forming various conditions with respect to the predicted density of the density controlling marks 27K and 27M, and forming the position detecting mark in the same color with the density controlling marks 27K and 27M based on the image forming various conditions after the change. In such a case, since the position detecting mark adopting for the color slip correction is got through the density collection, the highly precise color slip correction can be performed.

Title: Triangulation method
IPC: G01C3/06
Filed: 1992-03-17
Abstract: PURPOSE:To minimize the observation value to be compensated for attitude fluctuation by measuring directional cosine vectors from two sensors to a target, using their vector product as an observation value, calculating a parallax between the sensors, determining the direction of the target from each sensor middle point-, and calculating an average distance in combination with the distance between the sensors. CONSTITUTION:Directional cosine vectors sigma1, sigma2 are measured by passive sensors 1, 2, respectively, and their vector product upsilon1.2 is stored and held. The sigma1.2 is hourly compensated for attitude fluctuation. After a plurality of observations, the average of the held upsilon1.2 is determined. According to the equation ¦upsilon1Xupsilon2¦=¦upsilon1x2¦=sinzeta, a parallax S is determined. The directions theta1, theta2 of the target 3 from the sensors 1, 2 are determined according to the measured upsilon1, upsilon2, and these are averaged to provide the approximate value of the direction sigmaof the target 3. When L is the distance between the sensors 1, 2, and R is the average distance from the sensors 1, 2 to the target 3, R can be determined by an equation. According to this method, the observation value to be compensated for attitude fluctuation is only the vector product of the vectors sigma1, sigma2 and the calculation is halved, compared with a conventional method.

Abstract: PURPOSE:To obtain estimated target speed having a small delay due to accelerated motion of the target using a 4th proportional element and a 5th adder. CONSTITUTION:A 4th proportional element 12 and a 5th adder 18 which obtain a target estimated speed are provided to a tracking filter which inputs a target observing position to obtain a target estimated position and the target estimated speed. Then the speed correction is added to a target smoothing speed in proportion to an estimated error. That is, the target estimated speed is corrected in proportion to the estimated error and by a prescribed value compared with the target smoothing speed. Thus the delay caused by the accelerated motion of the target is reduced. As a result, it is possible to obtain a estimated target speed having a small delay due to the accelerated motion of the target.

Title: Sample liquid discharging equipment

IPC: H01J27/02
Filed: 1994-03-30
Abstract: PURPOSE:To eliminate the fluctuation when supplying a sample to a plasma torch for the stable supply of it by forming a waste container into a closed structure and then atomizing the sample liquid and providing a continuity pipe between a container supplying the sample liquid to a plasma and the waste container. CONSTITUTION:A sample liquid 1 is atomized through a neblizer 2 and is partially supplied to a torch 5 and then the remainder flows to a waste container 10 via an exhaust pipe 8 from a spray chamber 4 as waste. At this time, the volume of the effluent and the volume of the chamber 4 change. However, since the container 10 and the chamber 4 are connected via a continuity pipe 11, both are under the same pressure and at the same time the volume change in the chamber 4 is canceled out. Namely, the liquid surface of the container 10 rises and the volume at the space part decreases and then the gas at that part returns via the chamber 4 through the continuity pipe 11 by the same volume as the effluent. Therefore, the internal pressure in the chamber 4 does not change along with the flow and the liquid from the chamber 4 is unloaded due to the water level difference between the chamber 4 and the container 10.
